PD#172483
Problem:
To avoid A73 core speculative data loading from protected
memory, which triggers SError fault, the mapping of the
protected region should be cleared. In codec_mm driver, the
page structure pointer used to clear the mapping is wrong.
Although the memory is allocated from CMA, because we are
using CMA_res mode the address from CMA_res_pool is actually
a physical address, similar as reserved memory case. As a
result, the mapping to protected address is not cleared.
Solution:
1.Add "mem->from_flags ==
AMPORTS_MEM_FLAGS_FROM_GET_FROM_CMA_RES" case processing.
Verify:
Run YTTV and there is no SError crash after the fix.

Problem:
printk_prefix() passes NULL buf to print_time() to get the length of
the time prefix; when printk times are enable, the current code just
return "snprint(NULL, 0, "[%5lu.000000]", (unsigned long)ts)"
but in the SMP case, we add cpu core id at the end of time prefix, the
format is "[%5lu, %06lu@%d]", this gives a wrong size(shorter).
this will make buf get out of boundary, when run dmesg.
Solution:
replace [%5lu.000000] with [%5lu.000000@0]

Problem:
For the previous Amlogic CPU series(before TXLX), the CPU booting vector
locates at physical address starting from 0x00. To avoid influencing cpu
booting procedure, we have to reserve the first 1MB physical memory. But
it has changed since TXLX, the normal text section can safely use 0~1M
physical address. So it's no need to reserve the first 1MB in DTS.
Solution:
Change the starting address of usable memory from 0x100000 to 0x0 for CPU
series coming after TXLX.
